Technical Field

[0001] This utility model relates to the field of electrostatic protection technology, specifically an antistatic device. Background Technology

[0002] In today's booming modern textile industry, the applications of household textiles are becoming increasingly diverse, ranging from cozy bedroom bedding to elegant living room curtains. However, static electricity remains a persistent problem throughout the production, processing, and daily use of textiles. Static electricity not only makes fabrics prone to attracting dust, affecting their appearance and cleanliness, but it can also cause electric shocks to users upon contact, significantly reducing comfort. In some specific scenarios, static buildup can even pose safety hazards. Although various anti-static production processes exist in the industry, they are mostly focused on the fabric production stage, with insufficient attention paid to the ongoing anti-static needs after the fabric enters the home. Household textile anti-static grounding devices were developed to fill this gap, effectively conducting static electricity to the ground through grounding, eliminating static disturbances, and ensuring the quality and safety of textiles throughout their entire lifecycle.

[0003] The existing antistatic devices have insufficiently secure contact with textiles, making them prone to loosening and detachment. Extensive research by the inventors has revealed that even if the existing antistatic devices appear to be firmly connected, they still have the following drawbacks: some household antistatic devices cannot display resistance values, making it impossible for users to determine whether the device is effectively connected; poor connection stability, with insufficient fit at the connection point leading to loosening, resulting in reduced conductivity and poor antistatic effect. Utility Model Content

This ensures that static electricity from household textiles during use can be effectively conducted to the ground, guaranteeing the comfort and safety of textiles in home use scenarios and improving the user experience.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] like Figures 1-6 As shown, the antistatic device of this utility model includes: an upper pressing assembly 1 and a lower pressing assembly 2; the upper pressing assembly 1 is connected to the lower pressing assembly 2 through a connecting frame 3; the upper pressing assembly 1 and the lower pressing assembly 2 cooperate to complete the pressing action; the upper pressing assembly 1 includes a mounting plate 11, an elastic element 12 and a conductive component 13; the mounting plate 11 is provided with a plurality of mounting holes 111, the mounting holes 111 are used to fix the elastic element 12; the conductive component 13 is connected to the elastic element 12; the lower pressing assembly 22 includes a conductive cover 21; the conductive cover 21 is adapted to the conductive component 13, and the elastic element 12 makes the conductive component 13 and the conductive cover 21 tightly pressed together.

[0030] Understandably, such as Figure 3 As shown, it mainly consists of an upper pressing assembly 1 and a lower pressing assembly 2. The upper pressing assembly 1 and the lower pressing assembly 2 are stably connected by a flexible connecting frame 3 to ensure the coordination and buffering of the pressing action. The upper pressing assembly 1 includes a mounting plate 11, an elastic element 12, and a conductive component 13. The mounting plate 11 has several mounting holes 111 for fixing the elastic element 12. The elastic element 12 is made of a highly elastic material, with one end rigidly connected to the conductive component 13 and the other end fastened to the mounting plate 11 through the mounting holes 111 to form an elastically deformable pressing drive structure. The conductive component 13 is embedded in the inner bottom surface of the mounting plate 11. In one embodiment, the adaptive pressure adjustment range of the conductive component 13 when in contact with the fabric is 0.5-1.2N.

[0031] The core of the lower pressing assembly 2 is the conductive cover 21, whose surface is precisely adapted to the contact surface of the conductive assembly 13. Through the elastic pressure of the elastic element 12, the conductive assembly 13 and the conductive cover 21 are tightly fitted during the pressing process, forming a low-resistance conductive path. In one embodiment, the upper pressing assembly 1 and the lower pressing assembly 2 combine rigid support and elastic buffering through a flexible connecting frame 3. Combined with the high elasticity of the elastic element 12, the contact pressure between the elastic element 12 and the conductive assembly 13 is ≥0.5N, avoiding the loosening problem of traditional snap fasteners. Simultaneously, it ensures that the conductive assembly 13 and the conductive cover 21 remain tightly fitted during the pressing process, effectively preventing contact loosening caused by vibration or mechanical displacement. Furthermore, multiple experiments have shown that it operates stably in environments ranging from -10℃ to 70℃, and even at -10℃, the contact stress of the conductive assembly 13 still maintains a pressure of ≥0.4N, with a resistance detection error of <5% at 80% humidity. Under conditions of 80% humidity and 25℃, the resistance detection error is less than 3%, and the green light breathing mode trigger accuracy is 100%.

[0032] In a preferred embodiment, the conductive component 13 includes a conductive frame 131 and a sensing sheet 132; the conductive frame 131 is provided with a plurality of placement slots 1311 for placing the sensing sheet 132, and the surface of the sensing sheet 132 is provided with raised textures 1321; a square groove 31 is provided at the bend of the connecting frame 3, and a bending member 32 is fitted into the square groove 31, and the bending member 32 is provided with a plurality of wire channels 321; the wire channels 321 are used for inserting wires.

[0033] Specifically, the conductive component 13 includes a conductive mounting plate 131 and a sensing sheet 132 with raised textures 1321 on its surface. The textures 1321 significantly increase the contact area, ensuring that the static contact resistance remains stable below 1Ω. Simultaneously, the continuous elastic pressure of the elastic element 12 further reduces resistance fluctuations under dynamic operating conditions, ensuring long-term stable conductivity. The bending portion of the connecting frame 3 is provided with a square groove 31 and a nested bending element 32. The bending element 32 has a built-in wire channel 321, facilitating the laying and fixing of the grounding wire. Through the above structure, this device achieves both high-stability connection and efficient static electricity discharge during the pressing action, while also possessing wear-resistant and anti-loosening characteristics, making it suitable for electrostatic protection needs in various scenarios.

[0034] In a preferred embodiment, the upper pressing assembly 1 further includes a first housing 14, on which a fixing part 141 for fixing the elastic member 12 is provided, and the conductive assembly 13 is connected to the first housing 14 through the elastic member 12.

[0035] Understandably, such as Figure 4As shown, the upper pressing assembly 1 further includes a first outer shell 14, the surface of which is provided with a dedicated fixing part 141 for precisely positioning and fixing the elastic element 12. The fixing part 141 is rigidly connected to the bottom of the elastic element 12, ensuring that the elastic element 12 does not shift or deflect during the pressing action, thereby maintaining the alignment accuracy between the conductive assembly 13 and the conductive cover 21 of the lower pressing assembly 2. The conductive assembly 13 is indirectly fixed to the inside of the first outer shell 14 through the elastic structure of the elastic element 12, forming a three-level conduction path from the outer shell to the elastic element to the conductive assembly, which achieves both mechanical stability and optimizes electrostatic discharge efficiency.

[0036] In a preferred embodiment, the first housing 14 is provided with a first groove 142 and a second groove 143; the first groove 142 is used to install a switch 144; the second groove 143 is used to install a display module 145; the display module 145 includes an indicator light 1451 and a buzzer 1452.

[0037] Understandably, the first housing 14 has independent first recess 142 and second recess 143 inside, used to integrate the switch 144 and the display module 145, respectively. The first recess 142 is located at the front end of the housing, and can precisely embed and fix the switch 144 to avoid displacement caused by mechanical vibration; the second recess 143 is on the same horizontal line as the first recess 142, and the depth of the second recess 143 is adapted to the display module 145, achieving a simple appearance design. The display module 145 includes an indicator light 1451 and a buzzer 1452. The wiring terminals of the display module 145 are connected to the circuit board 24 through the wiring channel reserved at the bottom of the first housing 14, simplifying the assembly process. This structure not only optimizes the utilization of internal space, but also achieves a deep integration of functional zoning and user interaction, significantly improving the reliability and intuitiveness of the device.

[0038] In a preferred embodiment, the pressing assembly 2 further includes a second outer shell 22 and a third outer shell 23. The conductive cover 21 is sleeved on the second outer shell 22. The second outer shell 22 and the third outer shell 23 clamp one end of the connecting frame 3. The inner surface of the second outer shell 22 and the third outer shell 23 form a receiving cavity. A circular groove 231 is provided on the third outer shell 23 for placing the energy storage assembly 25. A rear end cover 232 is provided on the outer surface of the third outer shell 23 for protecting the energy storage assembly 25.

[0039] Understandably, such as Figure 2As shown, the pressing assembly 2 further includes a second housing 22 and a third housing 23, wherein the second housing 22 and the third housing 23 are fixed to one end of the connecting frame 3 by clamping, forming a stable mechanical connection. The conductive cover 21 is fitted onto the outer surface of the second housing 22 with an interference fit to ensure low resistance characteristics of the conductive path during pressing. A cavity is formed between the inner surface of the second housing 22 and the third housing 23 for receiving the integrated circuit board 24 and the energy storage component 25. The inner side of the third housing 23 is provided with a circular groove 231, the diameter of which matches the shape of the energy storage component 25. In one embodiment, the energy storage component 25 is a cylindrical lithium battery, and the circular groove 231 enables precise fixing and quick replacement of the energy storage component. A removable rear end cover 232 is provided on the outer side of the third housing 23, which adopts a dustproof and waterproof design and is connected to the third housing 23 by threads or buckles, providing multiple protections for the energy storage component 25. This structure, through its layered layout and modular assembly, ensures the safety and heat dissipation requirements of internal components while simplifying the maintenance process, making it suitable for long-term stable operation in industrial high-frequency vibration and complex home environments.

[0040] In a preferred embodiment, the third housing 23 is provided with a mounting post 233 for fixing a circuit board 24. The circuit board 24 is disposed on the inner surface of the second housing 22 and forms a receiving cavity with the third housing 23. The circuit board 24 includes a power module 241, a control module 242, and a protection module 243; the power module 241 is connected to the control module 242 and the protection module 243 respectively.

[0041] Understandably, such as Figure 6 As shown, the third housing 23 has multiple mounting posts 233 for fixing the circuit board 24. The circuit board 24 is vertically fixed to the cavity formed by the inner surface of the second housing 22 and the third housing 23 using screws or pins, ensuring the stability of the circuit board 24 under vibration. The circuit board 24 integrates a power module 241, a control module 242, and a protection module 243. The power module 241 serves as the core power supply unit, connected to the control module 242 and the protection module 243 via internal wiring to form a complete circuit system. The power module 241 converts the electrical energy provided by the energy storage component 25 into an appropriate voltage. The control module 242 adjusts and activates the display module 145 via commands. The protection module 243 monitors current and voltage parameters in real time and cuts off the circuit in case of overload or short circuit to prevent equipment damage. Through this design, the modular layout of the circuit board 24 combined with the rigid support of the mounting posts 233 optimizes space utilization and improves the safety and response efficiency of system operation, meeting the high reliability requirements of industrial and household scenarios.

[0042] In one embodiment, the display module 145, when activated by the control module 242, includes the following lighting modes:

[0043] When the resistance value is ≤200Ω: Indicator light 1451 displays green light and stays on for 10 seconds, buzzer 1452 sounds a long sound, at which time the frequency of buzzer 1452 is 2.7kHz and the duration is 2 seconds;

[0044] When the resistance value is greater than 200Ω: Indicator light 1451 displays green light and flashes for 0.5 seconds, and buzzer 1452 beeps twice. At this time, the frequency of buzzer 1452 is 2.7kHz and the duration of each beep is 0.5 seconds.

[0045] When a circuit break occurs: indicator light 1451 displays a red light and flashes for 0.25 seconds, and buzzer 1452 sounds rapidly at a frequency of 2.7kHz for 10 seconds.

[0046] In one embodiment, the protection module 243 includes a self-resetting fuse. In this embodiment, the self-resetting fuse is a PPTC RXEF050. The self-resetting fuse is connected in series in the control module 242. When the abnormal current is ≥0.5A, the self-resetting fuse of the protection module will disconnect within 10ms and automatically reset within 60 seconds.

[0047] When the pressure on the conductive component 13 is less than 0.4N, the indicator light 1451 will trigger a red light and flash, and the buzzer 1452 will sound an alarm.

[0048] In a preferred embodiment, the upper pressing component 1 and the lower pressing component 2 are made of ABS+PC material, and the connecting frame 3 is made of silicone.

[0049] Understandably, the main structure of the upper pressing component 1 and the lower pressing component 2 is injection molded from ABS+PC composite material. This material combines the toughness and impact resistance of ABS with the high strength and weather resistance of PC. It can withstand the repeated mechanical stress during the pressing process and also has excellent insulation properties, effectively isolating external electromagnetic interference. In one embodiment, the upper pressing component 1 and the lower pressing component 2 are connected by a connecting frame 3, with a pull-in force of 3-5N. The connecting frame 3 is integrally molded from high-elasticity silicone. Its flexibility provides a buffering effect during the pressing process, reducing the rigid impact between components. At the same time, the aging resistance of silicone ensures the connection stability and deformation recovery ability during long-term use.

[0050] In one embodiment, the core component of the conductive assembly 13, the sensing sheet 132, is made of a copper-nickel alloy foil with a thickness of 0.2 mm. Its ultra-thin design maximizes the contact area by using precisely etched raised textures 1321 on the surface while ensuring mechanical strength, reducing the static contact resistance to below 0.8 Ω and maintaining a low-resistance conduction state under dynamic conditions. This thickness specification can adapt to the deformation requirements of high-frequency pressing operations while avoiding the vulnerability caused by excessive thinness, achieving a balance between conductivity efficiency and durability.

[0051] The synergistic effect of the aforementioned materials and structural design enables the device to operate stably in both industrial high-frequency pressing and complex home environments, significantly improving its anti-static performance and service life.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
